Since the fluid pressure is applied to open-close process, the ball-type check valve is suitable in the high pressure condition. Especially, it is essential for ball-type check valve to design the response speed related with ball size, ball mass, flow rate from pump. Flow rate defines the closing time. And the closing time must to shorter than the stroke time for plunger. In this paper, we suppose the equation to calculate the response speed, and then we applied this equation to the check valve really being used. Based on this equation, the check valve will have been designed.
